THE Princess Royal is being prosecuted under the Dangerous Dogs Act after her pet bull terrier attacked a couple in Windsor Great Park, it was confirmed yesterday.

Anne and her husband, Commodore Tim Laurence, have been summoned to appear before East Berkshire magistrates in 10 days' time, said Buckingham Palace.

The couple face possible penalties of fines of up to &#xA3;5,000 each and up to six months' imprisonment.

Magistrates can also order the destruction of the animal and have the power to disqualify the Princess and her husband from keeping a dog.

A Buckingham Palace spokesman refused to discuss details of the alleged incident but said, "We can confirm that the Princess Royal and Commodore Tim Laurence have received a summons to appear before magistrates in due course."

Thames Valley Police would not confirm or deny that the alleged incident had taken place, saying it was not their policy to identify anyone who had received a summons until they appeared before a court.

A spokesman said, "If someone has not been charged, we are not prepared to release any names or information."

The Mail On Sunday reported that the incident happened in July when Anne, 52, and her husband were exercising the dog in the park.

It was reported that the animal was allowed off its lead and attacked an man and woman.

One of them was allegedly bitten on the leg, though not seriously, and police were alerted, the newspaper said.

It is understood it is the first time such a senior royal has been summoned to appear before a criminal court for an offence other than exceeding the speed limit.

The newspaper said the hearing was set for Wednesday, October 9, at Slough Magistrates Court, when it would be disclosed whether the couple would plead guilty or not guilty.
